Interference elimination system and interference eliminating method

An interference elimination system for eliminating from a first radio signal transmitted from a first radio terminal to a first radio base station, the effect of interference due to a second radio signal transmitted from a second radio terminal to a second radio base station, said system comprising:

• an extractor in said second radio base station, said extractor extracting said second radio signal from radio signals received in said second radio base station;
• a transmitter in said second radio base station, said transmitter transmitting said extracted second radio signal to said first radio base station;
• and
• an interference eliminator in said first radio base station, said interference eliminator eliminating said second radio signal transmitted from said second radio base station, from radio signals received in said first radio base station.
